摘　　要：为了实现监测工程岩体灾变失稳情况,以某露天矿采场边坡为例,构建了一套以表面位移在线监测为主,内部位移手动监测和裂隙变形在线监测为辅的监测系统。结果表明:基于测量机器人技术的表面位移在线监测系统能够满足采场边坡日常变形监测工作需要,采用钻孔测斜法能够获取采场边坡岩体内部变形情况,利用裂隙传感器能够实现采场边坡裂隙变形监测分析。无论表面位移和裂隙变形在线监测,还是内部位移手动监测,只有长时间持续监测,才能实现采场边坡灾变预警的目的。In order to monitor the catastrophic instability of the engineering rock mass,taking the slope of an open-pit mine as an example,a set of monitoring system was constructed with surface displacement online monitoring as the main part,internal displacement manual monitoring and fissure deformation online monitoring as supplementary.The results show that the surface displacement online monitoring system based on the measurement robot technology can meet the needs of daily deformation monitoring of stope slope.The borehole inclinometer method can be used to obtain the internal deformation of stope slope rock mass,and the fracture sensor can be used to realize the monitoring and analysis of the fracture deformation of stope slope.Whether the surface displacement and fracture deformation are monitored online or the internal displacement is monitored manually,only long-term continuous monitoring can achieve the purpose of early warning of stope slope disaster.
